What Fox Corporation told the SEC could break it.

Fox's owned/operated broadcast TV stations and FOX Network are heavily regulated by the FCC under the Communications Act (licensing, national ownership caps, channel-sharing), and regulatory changes could constrain operations.

“The television broadcast industry in the U.S. is highly regulated by federal laws and regulations issued and administered by various agencies, including the FCC. The FCC regulates television broadcasting, and certain aspects of the operations of cable, satellite and other electronic media that compete with broadcasting, pursuant to the Communications Act of 1934, as amended (the “Communications Act”).”

Fox's linear-TV advertising sales depend on Nielsen's statistical sampling as the primary audience-measurement methodology; if measurement does not accurately reflect viewership, advertising sales could be negatively affected.

“Although Nielsen's statistical sampling method is the primary measurement methodology used for our linear television advertising sales, we measure and monetize our digital platforms based on a combination of internal and third-party data, including demographic composite estimates.”

Fox's revenue depends on protecting its content IP; piracy and signal theft (and the scope/duration of IP rights under varying US and foreign laws) could reduce revenue or raise enforcement costs.

“The Company takes a variety of actions to combat piracy and signal theft, but the protection of the Company's intellectual property rights depends on the scope and duration of the Company's rights as defined by applicable laws in the U.S. and abroad and how those laws are construed.”
